The Airthings Wave Plus is the more capable radon monitor of these two because it measures CO2, TVOC and pressure as well and works with Alexa, Google Home and Home Assistant. The X-Sense XR0A-iR Wi-Fi Radon Detector answers with built-in Wi-Fi, an LCD screen, two years on 3x AA batteries and a lower price, but it measures radon, temperature and humidity only and reports to its own app. The Airthings Wave Plus is Bluetooth only and has no screen, so continuous remote data needs an Airthings hub. Choose the Airthings Wave Plus for a broader air picture in a smart home, and the X-Sense XR0A-iR for a simple radon meter you can read on its screen and check from your phone.

What the differences mean

What it measures

The Airthings Wave Plus reads radon, CO2, TVOC, temperature, humidity and atmospheric pressure. The X-Sense XR0A-iR reads radon, temperature and humidity, so it is a radon meter, not an air quality monitor.

Wi-Fi and the hub

The X-Sense XR0A-iR connects to 2.4 GHz Wi-Fi on its own and pushes alerts to its app. The Airthings Wave Plus is Bluetooth only, so continuous data and remote access mean adding an Airthings hub.

On-device screen

The X-Sense XR0A-iR has an LCD for its radon readings. The Airthings Wave Plus has no screen at all: you wave at it for a Good, Fair or Poor light or read the app.

Battery life

The X-Sense XR0A-iR runs about 2 years on 3x AA batteries and the Airthings Wave Plus about 1.5 years on 2x AA batteries. The gap is small and neither needs a cable.

Voice assistants and Home Assistant

The Airthings Wave Plus works with Alexa, Google Home and Home Assistant. The X-Sense XR0A-iR has no voice assistant support and Home Assistant is not documented, so it lives inside its own app.

What owners say

Airthings Wave Plus owners like getting six measurements in one battery-powered, good-looking unit. They describe the VOC and CO2 readings as responsive, moving visibly when they sweep, open a window or carry boxes in from storage, and many bought it for radon and credit it with confirming a problem and justifying mitigation. Their complaints cluster around two things: it is Bluetooth only, so continuous recording and remote access need an Airthings hub, and the app and syncing can be slow, sometimes showing days-old data. Several who compared it with charcoal lab kits and another radon monitor found the radon numbers reading low, and it needs a week or more of calibration, so owners treat radon as a trend and confirm with a lab kit when precision matters.
